Storm Alert

Weather forecasts are calling for heavy rain, thunderstorms, gusty winds, and the potential for flash flooding in Massachusetts today. National Grid is prepared and we urge you to be safe and ready, too. It is a good idea to always keep several working flashlights and an extra supply of batteries in your home. We also recommend charging mobile devices prior to the storm so you can stay connected in the event of a power outage.

Better control of your facility’s energy use is often as easy as flipping a switch. Get started with these tips.

Data centers use 2 percent of the electricity in the United States. Make your data center more efficient with these improvements:

  • Save energy with server power-management software, which enables servers to go into standby mode when not in use.
  • Go virtual. Improve your energy efficiency and use less equipment by utilizing a host server to run multiple operating systems and applications.
  • Upgrade your servers to ENERGY STAR® qualified models. In recent tests conducted by the EPA, Hewlett-Packard, and Microsoft, new ENERGY STAR servers used 54 percent less power than some older models.
  • Make use of more efficient uninterruptible power supply (UPS) units.
  • Adjust your data center’s layout to alternate hot aisles and cold aisles, which improves air flow.
  • Follow ASHRAE Technical Committee 9.9 temperature and humidity guidelines. For Class 1 and Class 2 data centers, this means a temperature between 68 and 77° F and 40 to 55 percent relative humidity, with a maximum temperature change per hour of nine degrees.
  • Use an outside air or waterside economizer, air-to-air heat exchanger, or dry cooler to cool your data center.
